*2. DIP SW setting is required for PC configuration type.
*3. Frequency range must be 0 – 100 Hz or higher. 0 –
1
kHz or higher for sinusoidal waveform input. Frequencies
lower than 10 Hz may be out of accuracy conformance.
*4. For sinusoidal waveform input with the pulse ampli
-
tude smaller than 1V p-p, the frequency range must be 0
– 1 kHz or higher, or extend the sampling time by using
the PC configurator software.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) DIP SW setting: Check that the switches are set to ap
-
propriate positions.
3) Power input voltage: Check voltage across the terminal
10 – 12 (AC) or 11 – 12 (DC) with a multimeter.
4) Input: Check that the input signal is within 0 – 100% of
full-scale.
5) Output: Check that the load resistance meets the de
-
scribed specifications.
MAINTENANCE
Regular calibration procedure is explained below:
■
CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit using the PC Configurator
Software (model: M3LPACFG).
